我的jqquery如下所示:
var chart;
$(document).ready(function () {
var options = {
chart: {
renderTo: 'container',
defaultSeriesType: 'line',
marginRight: 130,
marginBottom: 25
},
title: {
text: 'Monthly Average Temperature',
x: -20 //center
},
subtitle: {
text: 'Source: WorldClimate.com',
x: -20
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
yAxis: {
title: {
text: 'Temperature (°C)'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
formatter: function () {
return '<b>' + this.series.name + '</b><br/>' +
this.x + ': ' + this.y + '°C';
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -10,
y: 100,
borderWidth: 0
},
series: []
};
//Calls the JSON
jQuery.getJSON("GetLineData", null, function (items) {
var series = {
name: '',
data: []
};
jQuery.each(items, function (itemNo, item) {
//Get the items from the JSON and add then
//to the data array of the series
series.data.push({
name: item.Key,
data: item.Value
})
});
options.series.push(series);
//Create the chart
chart = new Highcharts.Chart(options);
chart.render();
});
});
var图;
$(文档).ready(函数(){
变量选项={
图表:{
renderTo:'容器',
defaultSeriesType:“行”,
marginRight:130,
marginBottom:25
},
标题:{
文字:“月平均气温”,
x:-20/中心
},
副标题:{
文字:“来源:WorldClimate.com”,
x:-20
},
xAxis:{
类别:[‘一月’、‘二月’、‘三月’、‘四月’、‘五月’、‘六月’,
‘七月’、‘八月’、‘九月’、‘十月’、‘十一月’、‘十二月’]
},
亚克斯:{
标题:{
文字:“温度(摄氏度)”
},
绘图线:[{

宽度:1,
颜色:'#808080'
}]
},
工具提示:{
格式化程序:函数(){
返回“+this.series.name+”
+
这个.x+':'+这个.y+'C';
}
},
图例:{
布局:“垂直”,
对齐:“右”,
垂直排列:“顶部”,
x:-10,
y:100,
边框宽度:0
},
系列:[]
};
//调用JSON
getJSON(“GetLineData”,null,函数(项){
变量系列={
名称:“”,
数据:[]
};
每个(项,函数(项号,项){
//从JSON中获取项目,然后添加
//到系列的数据数组
series.data.push({
名称:item.Key,
数据:item.Value
})
});
选项。系列。推送(系列);
//创建图表
图表=新的高点图表。图表(选项);
chart.render();
});
});
图表显示时没有错误,但也没有两条线。
我猜这个系列的制作方法不对吧?提前感谢您的帮助。我想您所需要做的就是
options.series.push(series);
做
或者您可以将整个数组作为单个项目推送到一个数组中试试这个。我假设item.Value是一个数组,可以用作提供给图表的数据
//Calls the JSON
jQuery.getJSON("GetLineData", null, function (items) {
var series = [];
jQuery.each(items, function (itemNo, item) {
//Get the items from the JSON and add then
//to the data array of the series
series.push({
name: item.Key,
data: item.Value
})
});
options.series = series;
//Create the chart
chart = new Highcharts.Chart(options);
chart.render();
});
使用,您无需考虑如何将数据从action方法传递到javascript。您可以在服务器端构建和绑定所有内容。以下是此库的基本行示例:
